Abstract

Provided is a refrigerator. The refrigerator includes a compressor (110) compressing a refrigerant, a condenser (120) condensing the refrigerant compressed in the compressor (110), a refrigerant tube (100) guiding a flow of the refrigerant condensed in the condenser (120), an expansion device (141) decompressing the refrigerant condensed in the condenser (120), and an evaporator (150) evaporating the refrigerant decompressed in the expansion device (141). The evaporator (150) includes an evaporation tube (152) through which the refrigerant decompressed in the expansion device (141) flows, a coupling tube (172) through which a refrigerant heat-exchanged with the refrigerant of the evaporator (150) flows, and a heat-exchange fin (154) coupled to the evaporation tube (152) and the coupling tube (172).
